Here's a few pictures of my cichlids with my new lens, the Tamron 17-50mm f/2.8. I'm completely in love with this lens, and have hardly taken it off my camera since I got it
Here's a half decent one (finally) of my sub-sub dominant male Saulosi. The sub-dominant male has been making a go for king of the tank, and the current dominant male is giving him a run for his money, so this guy has been a bit less shy, since he's not getting picked on as much now. You can see a bit of yellow fringing around his fins, and a just a faint hint of black barring on his side.
Here's Sonic, my male Red Empress.
And, the obligatory 'showing off my new lens' shot (100%!!! blows the kit lens out of the water)
This one was taken at 17mm. You can see the dominant male Saulosi on the far left, and the blue and black one top right is the sub-dominant male, the two yellow ones are female Saulosi. The brown fish in the front is a sub-dominant male rusty.
